Attackers can place local or private-network URLs behind hoverable links to route authenticated requests through the daemon, potentially accessing sensitive internal endpoints when users interact with attacker-controlled content.","published":"2026-05-18T19:00:54.115Z","modified":"2026-08-12T03:51:45.305404862Z","cvss":null,"epss":{"score":0.0033,"percentile":0.25763,"asOf":"2026-08-14"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"@steipete/summarize","fixedVersion":"0.15.1"}],"fix":{"url":"https://github.com/steipete/summarize/commit/ecbb2c414255aa480a15d0d8b205224c14cfdbcb","label":"steipete/summarize@ecbb2c4"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45245.json"},{"type":"ADVISORY","url":"https://github.com/steipete/summarize/releases/tag/v0.15.2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45245"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/summarize-unauthorized-daemon-request-via-untrusted-events"},{"type":"REPORT","url":"https://github.com/steipete/summarize/pull/218"},{"type":"FIX","url":"https://github.com/steipete/summarize/commit/ecbb2c414255aa480a15d0d8b205224c14cfdbcb"},{"type":"PACKAGE","url":"https://github.com/steipete/summarize"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:45.305404862Z"}}
